Why the COVID vaccine is incorrectly associated with infertility

January 12, 2021-There is no evidence that a new vaccine against COVID-19 causes infertility, but there are still concerns cited as a reason some healthcare professionals are reluctant to give their first injections.

A significant number of healthcare professionals across the country oppose the availability of new vaccines.

Ohio Governor Mike DeWine said in a recent briefing that 60% of Ohio’s nursing home staff rejected the shot. In Georgia, an infection prevention nurse who adjusts the COVID vaccine for 30,000 employees in her healthcare system said less than 33% had been shot so far. The rest decided to “wait and see”. The nurse was not allowed to talk to the reporter, so she disclosed the number on the condition that she did not reveal which hospital she worked for.

The University of Minnesota, a pediatric infectious disease specialist at the University of Minnesota, who studies vaccine repellent, is not surprised by Dr. Jill Foster, MD.

“At COVID, it was a perfect storm. For COVID, there were already a lot of people saying that there was no such thing as COVID, no worse than the flu,” she says. Many of those people have gained considerable support for themselves on social media. When vaccines came out, they used those platforms to stir up conspiracy theories.

Where did this infertility myth come from?

In early December, German doctor and epidemiologist Wolfgang Wodag, who was skeptical of the need for vaccines in other pandemics, worked with a former Pfizer employee to work with the European Pharmacy (FDA’s European Union counter). I asked the part) to postpone it. Research and approval of Pfizer / BioNTech vaccine. One of their concerns was a protein called cincitin-1. It shares similar genetic directives as some of the new coronavirus spikes. That same protein is an important component of the mammalian placenta. They also argued that if the vaccine causes the body to make antibodies against syncitin-1, the body may attack and reject proteins in the human placenta, making women infertile.

Their petition was picked up on blogs and websites against vaccination and posted on social media. Facebook eventually removed the post about the petition from the site for disseminating false information.

The idea that vaccines could be deployed for population control was also incorporated into the plot of a recent fictitious miniseries on Amazon Prime Video. Utopia.. At the show (spoiler caution), a drug company enthusiastic about population management creates the illusion of an influenza pandemic and persuades people to vaccinate against human reproduction rather than prevent infection.

A spokeswoman for Amazon Studios said the series was pure fiction.

“”Utopia It premiered on Amazon Prime Video on September 25, 2020, “a spokesman said in a statement to WebMD. “It was written seven years ago and shot before the COVID-19 pandemic. This series is based on the original UK version, premiered in 2013, and includes the same plot, including the vaccine storyline. I share a lot of. “

The show is creative and writing, but is it possible that such a thing happens in real life?

The biological basis for this idea is really unstable, says Foster.

The coronavirus peplomer and syncitrine-1 share a small stretch of the same genetic code, but not enough to match them. She says it’s like they both have a phone number that includes number 7. Even though their phone numbers shared numbers, they couldn’t dial one number to reach the other.

“What we know is that they are similar at such a small level,” says Foster.

Even Wolfgang wrote in his petition that “there is no indication that an antibody against the SARS virus’s peplomer acts like an anti-cincitin-1 antibody.”

Indeed, data from human studies of the Pfizer vaccine do not support this theory. In a Pfizer trial involving more than 37,000 women, women underwent a pregnancy test before being accepted into the study. If they were already pregnant, they were excluded. During the trial, 23 women probably became pregnant by accident. Twelve of these pregnancies occurred in the vaccine group and 11 in the placebo group. They continued to be tracked as part of the study.

Paul Offit, MD, director of the Vaccine Education Center at Philadelphia Children’s Hospital, said the idea was that more than 22 million people in the United States were infected with SARS-CoV-2, the virus that causes COVID. It is said that it is really crumbled. -19. In fact, experts believe that the number is much higher, as only 22 million people have been tested and found. Most people think that real numbers are at least three times higher.

Ofit says he believes that 70 million Americans, or about 20% of the population, are infected. If the infertility theory is true, he says, you would expect a body that makes antibodies to natural infections to appear in our infertility statistics. It’s not.

“There is no evidence that this pandemic has changed the birth pattern,” says Ofit.

Vaccines can cause disease-related biological effects, he says. Take measles as an example. After measles vaccination, small blood vessels called petechiae can break as a result of blood clotting problems. Although rare, it can occur. Measles, illnesses can also cause it, so vaccines cause that phenomenon, he says.

“If natural infections don’t alter fertility, why does the vaccine do it?” Says Ofit, who is considering the clinical trials behind the vaccine as an FDA adviser.

Offit acknowledges that it does not have all the long-term safety data needed for vaccines. This is currently being gathered violently as the vaccine has been deployed to millions of people and reported by the CDC.

But so far, he says, the main problem seems to be a severe allergic reaction that seems to occur very rarely-about 11 people for every 1 million doses given. so. He says that if that happens, people generally know immediately when they are still being monitored by nurses and doctors. Ofit says the reaction is severe but treatable. That’s one of the reasons the CDC advised people who are allergic to any part of the vaccine containing a related compound called PEG or polysorbate to avoid these first shots.

Bell’s palsy, which causes one side of a person’s face to sag temporarily, may be another rare risk. In clinical trials, this temporary paralysis occurred slightly more frequently in vaccinated people than in placebo vaccinated people, but Bell’s palsy cases are as common as the general population. It wasn’t. Currently, it is unknown whether it is a side effect of the vaccine.

Ofit says what people need to know is that they may feel pretty clumsy after a shot. He says he had about 12 hours of fatigue and fever after the recent vaccination. This is not a side effect, but the body creates a protective shield against the virus.

“It was a hit,” he says, “but again, it’s a small price to pay to avoid this virus.”
